A New Light on the History of the Cahamanas
By Dhirendra Chandra Ganguly
Summary
The Cahamanas ruled Sakambhari (Rajputana and Ajmer) from the 8th to 12th centuries. Prthviraja III, son of King Somesvara, faced Muhammad Ghori’s invasions in 1191 and 1192. Despite initial resistance, Ghori defeated the Cahamanas at the Second Battle of Tarain (1192), capturing and killing Prthviraja near Sursuti. Ghori installed Kola, son of the Rai of Ajmer, as a tributary ruler, but Hemraj, Prthviraja’s nephew, later expelled him. Kutb-ud-din Aibak subdued Hemraj, appointing his own governor in Ajmer. The *Hammira-Mahakavya* recounts Prthviraja’s alleged capture and release by Ghori, followed by Ghori’s conquest of Delhi (1193). Prthviraja’s overconfidence led to a decisive defeat, with his horse’s dance distracting him during battle. His brother Harirdja briefly ruled but died fighting Ghori. The *Viruddha-vidhi-vidbvamsa* colophon (12th century) links the Nagara dynasty to Somesvara’s lineage, detailing Skanda and Vimana, key ministers who served under Prthviraja. Key sources include Hasan Nizami’s *Taj-ul-Ma-asir*, Minhasurjit’s *Hammira-Mahakavya*, and the *Firishta*. The conflict marked the end of Cahamana dominance, with Ajmer falling to Muslim rule by 1192.
Conclusion
This study reconstructs the Cahamana-Muslim conflict through underutilized chronicles, revealing Prthviraja III's military overconfidence and strategic miscalculations during Muhammad Ghori's invasions. The analysis of *Taj-ul-Ma-asir*, *Tabakat-i-Nasiri*, and *Hammira-Mahakavya* highlights the decisive role of internal dissent and Ghori's psychological warfare, exemplified by the fateful battle where Prthviraja's distraction by a dancing horse sealed his capture. The findings underscore the fragility of regional kingdoms against centralized Muslim forces and the enduring legacy of Guvindaraja's later Ranthambore dynasty, established post-conquest. This research shifts focus from traditional Rajput narratives to the Cahamanas' complex political dynamics, emphasizing how fragmented historical sources, when synthes
